Optimal tumor size cut-off values according to cancer-specific survival by X-tile analysis. X-tile software was used to calculate the cut-off value of tumor size (A and B). The cohort was divided into low (purple), medium (gray), and high (blue) survival groups according to the cut-off value for tumor size (C). The cut-off value for tumor size was validated by Kaplan–Meier curve (D)
